Yes — this manual includes the full procedure for replacing the thermostat housing on the 2015 Mercedes-Benz A45 AMG (W176), along with detailed exploded diagrams, torque specs, and fastener locations to guide you through the job from start to finish.
The thermostat is mounted on the left side of the engine block, behind the turbo. You'll need to remove the air intake pipe and a few coolant hoses to access the housing. From there, the manual provides a breakdown of the bolts securing the thermostat assembly, and steps for cleaning and re-sealing the mating surface before installing the new unit. It also shows how to properly refill and bleed the cooling system afterward to avoid air pockets or overheating.
Whether you’re doing a simple swap or troubleshooting a more complex cooling system issue, the guide will walk you through it clearly and accurately.
